3D Shaped PDC cutters

Different shapes of PDC cutters(3D PDC cutters)are designed to have a smoother and more precise cutting edge, which have increased ROP, optimized cooling, better depth of cut and formation engagement.Choosing the right shape is very important, which can improve your working efficiency and reduce the drilling cost.

Application

With the increasing difficulty of drilling and the improvement of drilling efficiency, more and more shaped PDC inserts are used in oil and gas drill bits,DTH drill bit, cone bit, and diamond pick.

We can provide a shape that can perform in any number of applications and requirements. 

As a general rule, large cutters (19mm to 25mm) are more aggressive than small cutters. However, they may increase torque fluctuations.

Smaller cutters (8mm, 10mm, 13mm, and 16mm) have been shown to drill at a higher rate of penetration (ROP) than large cutters in certain applications. One such application is limestone for example. Bits are designed with smaller cutters but more of them can withstand higher impact loading.

Additionally, small cutters produce smaller cuttings while large cutters produce larger cuttings. Large cuttings may cause problems with the hole cleaning if the drilling fluid cannot carry the cuttings up.
